Real-time fabric inspection system using line camera

Quality inspection of textile products is an important problem for fabric manufacturers. This paper presents an automatic vision-based system for the quality control of web textile fabrics. Typical web material is 1-3m wide and is driven with speeds ranging from 20m/min to 200m/min. At presents the quality inspection procedure is manually performed by expert. However, they cannot detect more than 60% of the present defect and inspect the fabric if moving faster than 30m/min. To increase the overall quality and homogeneity of textile, an automated visual inspection system is needed for the productivity. Currently, the existing inspection systems are too expensive to purchase for small companies. In this paper, a PC based real-time inspection algorithm is proposed with low cost and high detection rate. The method shows good results for several types of fabric defects.
